Unable to connect to PC

[Eneswar]

Hey guys, I have been unable to connect my HP Prime to PC via connectivity kit for months. (I have been able to connect it in the past, maybe 1-2 years ago) I have tried it on multiple PCs on windows 11, windows 10, compatibility mode on windows 7. Hp prime turns on when I connect the USB but it refuses to appear in the app no matter what I have tried. Please help me

Are you using a charging only cable rather than a data cable such as the one supplied with the Prime?

Im pretty sure Im using the cable that came with the HP Prime, but now that you asked, im not 100% sure... It looks like this:

That makes sense, thank you.

Looking at a few unboxing videos I think the cable I have been using is a regular charging cable... I will have to see if I can find the other cable, or buy one from amazon.

Yes, this cable will work.

However the cable in the photo you posted does indeed look just like the cable that came with early Primes; it's rather uncommon for a cable to include the rubber boot, but the cable HP included with early Primes did have one just like shown.

) Your cable looks like the one that came with my G2 Prime.

) The connectivity kit installs a mini-networking protocol called "Bonjour" which can be blocked
by inapproriate firewall setting.

) Have you installed a third-party anti-virus or firewall program? They could be blocking
the Bonjour mini-networking protocol.

) You will have to get the HP Prime update from http://www.hpcalc.org, The intended server for
the Prime is not working at this time. The update will probabally have to be done manually.

But the few unboxing videos that I watched had two cables, one with the rubber boot where they said this was the charging cable, and one other cable. I dont know where that cable is right now so I ordered that one from amazon, hopefully that will work

I dont use any third party program just windows own, and I dont think I ever got any such warning. I will keep this in mind when I try with the new cable I just ordered! Thank you everyone who answered.

Early Prime kits also included a 2nd cable for unit-to-unit direct connection for exchanging data among devices. I'm not sure if a Prime kit still includes this 2nd cable, it's been > 11 years since I bought my Prime. Also, I understand Primes sold in EU don't include a power adapter (the justification is 'everyone has one already) and possibly not the USB cable either.

Have you tried rebooting the calculator (On+symb or the little reset button on the back)? I've had problems and general wierdness in the past around connecting it to a computer, but rebooting the calculator had always fixed them.

I have not honestly, I will keep this in mind, I should be getting my cable today and will be giving it a try.

[Eneswar]

Alright so I got the cable, reinstalled the app from https://www.hpcalc.org/details/8938. Connected everything and still HP Prime does not show up in the connectivity kit. I have tried to reset it (On+Symb), ran the app in admin mode, nothing

Is there any settings on the prime/kit I should look at?

Have you checked to verify if the Bonjour service is running? It shows up in TaskManager as mDNSResponder.exe.

Also, try suspending your AV/Security s/w firewall temporarily, it might be blocking the network comms used to connect.
